When water boils, the temperature remains constant at 100°C (at standard atmospheric pressure) because the added heat energy is used for the phase change from liquid to vapor rather than increasing the temperature. This energy is called the latent heat of vaporization. As heat is absorbed, water molecules gain enough energy to break free from the liquid state and enter the gaseous state, allowing the boiling process to occur without a rise in temperature.
What else can I help you with?
Does pure liquid boils at fixed temperature at a given pressure?
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.
When liquid boils its temperature remains the same so where does the heat go?
When a liquid boils, its temperature remains constant because the heat energy supplied is used for the phase transition from liquid to gas, rather than raising the temperature. This energy, known as the heat of vaporization, breaks the intermolecular bonds in the liquid, allowing molecules to escape into the gas phase. As a result, while the temperature stays steady, the added heat facilitates the transformation rather than increasing temperature.
How does the temp of water change as it boils?
Water stays at a constant temperature when it boils unless it is under pressure. More heat just makes it boils faster. The boiling temperature is around 212F or 100C varying somewhat with the altitude and the purity of the water.
Does a pure substance always boil at a fixed temperature?
Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.
When a sample of liquid boils thermal energy increases or decreases?
When a sample of liquid boils, thermal energy increases. This added thermal energy allows the molecules to overcome intermolecular forces and transition from the liquid phase to the gas phase. As a result, the temperature of the liquid remains constant during the boiling process, even though energy is being supplied.
Does pure liquid boils at fixed temperature at a given pressure?
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.
Why liquid boils at constant temperature at a given temperature?
Yes.
Why does the temperature remain constant when it boils?
A substance has different phases, but it only boils at a certain temperature. If it is over that temperature it will evaporate or if it is under that temperature it won't boil.
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.

What happens to the saturation temperature of the liquid refrigerant inside a refrigerant tank during system charging?
multiple choice: A: It rises B: It falls C: It remains constant D: It rises slightly, then remains constant. The answer is B The Vapor leaving the refrigerant tank is replaced by the liquid that boils off into vapor as the vapor being charged leaves the tank. The liquid saturation temperature drops as liquid boils to vapor. Example; The frost on a propane tank when you BBQ or use alot of propane for ???.

Why does the water in the pressure cooker boils even if the flame is put off?
The temperature remains high for a while.
